RI OAD-SURFACING MAGHINE.

Application filed November 15, 1921.

To all whom it may concern:

Be it known that we, JAMES R. MOORE and THOMAS B. Moons, citizens of theUnited States, and residents of Wichita, Kansas, have invented certainnew provements in Road-Surfacing Machines, of which the following is'adescription, referring to the drawings which accompany thisspecification.

The invention relates to a power operating road surfacing machine. Bythe use of our machine, a roadway may be out, smoothed desired grade preparatory for paving. Further and specific objects and functions of theinventlon will be disclosed in the description of the drawlngs, inwhich; Fig. 1 is a side view of the machine. Fig 2 is a lan viewthereof. Fig. 3 is a view taken a ong the line TIL-Ill in Fi 4 is asectional view taken along 5-H Fig. 3. Fig. 3 is also a view taken alongthe line EF -HI Fig. 4. Fig. 5 is a fragmentary detail side view of thecutter drum. Fig. 6 is a plan View of Fi 5. Fig. 7 is a detail View ofthe square en ed-rods and rod receiving sleeves seen in Fig. 2, withparts in section for clearness of decri tion. Similar numerals ofreference indicate corresponding parts throughout all the figures of thedrawings.

Referring to the drawings; centrally located at the rear of the frame ofthe machine is seen the engine 1 from which power is developed tooperate the road surfacing mech anism. The rear part of the machine is aduplicate of the ordinary caterpillar tractor and is provided with thecustomary clutch, transmission difierential and steerin mechanism, theengine 1 however also urnishing power for such tractor elements. Whenthe machine operates for road surfacing, the tractor transmission isplaced in neutral.

The engine 1 drives a shaft leading to the cone clutch 2 and on thisshaft is mounted a small sprocket wheel 3, Fig. 2. The internal part ofthe clutch 2 when in contact with the external part 4, drives the pinion5 which drives the ring gear 6 mounted on the transverse shaft 7. Ateachend of the shaft]? is rigidly mounted a small sprocket wheel, eachof equivalent diameter, and over the chains 8 and 8'. The

run the large sprocket 9 rigid on shaft 10", while a sprocket wheelsimilar to 9 and arranged at the opposite side of the drum is driven bythe chain 8 drives and useful lmteeth on the wheels 16 and 16'.

chain 8'. The shaft 10 is rigid with the cutterdrum 10.

The clutch 2, Fig. 2 is controlled by a lever arm 11 operated by theshaft 12 leadmg from the operating lever 13. In Figs. 3 and 4 is shownin" detail the ratchet mechanism for transmitting motion to thecaterpillar mechanism during road surfacing operations.

On the shaft 7 (see Figs 1, 2, 3 and 4), is mounted an eccentric 14which revolves in a ratchet member 15 which engages As seen in Figs. 1and 2, a short transverse shaft 17 rotates in bearings carried by theframe and carries the wheel 16, while the rigid on the shaft 17 axiallyaligned with the shaft 17 as seen in Fig. 4 and rotatin in hearings onthe frame. Note that the end of the shaft 17 rotates in the shaft 17' asa bearing, thus these shafts may rotate at dilferent speeds whennecessary.

On the outer end of the shaft 17 is rigidly mounted a sprocket wheel. 18and it will he understood that the outer end-of the shaftl? forward.

The cutter drum is held level and at the proper height by the followingdescribed 10* of the cutter 20 mounted on the mechanism. The shaft drumis held in bearings the recessed endof wheel 16 is hearing arms 21 and21; which are pivoted at 21, 21 on the ends of the shaft 7 The arms 22and 22 are riveted to the ends of the arms 21 and 21 and then continueon and out to the arms 21 and 21f where they again connect. Theintermediate por tion of the arms 22 and. 22' pivot. likewise at 22", 22on the shaft 7 The inner ends of each carry a pivoted screw membersuchas 23, 23*, Fig. 2, which receives the screw shafts the lower endsof these shafts 23 and 23 are rigidly afixed driva e conical elements 2323 of a reversible friction drive. The

23 and 23 and on shafts 24 24 Figs. 1 and 2, of this friction to extendinto sleeves 2st and 24 the receiving portions thereof being fashionedsquare to receive them as illustrated in Fig. 7, therefore these shaftscan slip back and forth in the sleeves. These sleeves are rigid to theshaft 25 rotatably mounted in bearings 25 25 intermediate the axiallyaligned shafts 24 24. On the shaft 25 is mounted a bevel gear wheel 26which is driven by a bevel gear wheel 27, mounted on the shaft 28. Atthe opposite end of the shaft 28 is seen a cone 29 of acone clutchmechanism, Figs. 1 and 2. This cone 29 being. slidably mounted on akeyway on the shaft 28. The outer member 29* of the cone clutchmechanism is driven by a chain 29" from the sprocket 3. By actuating thelevers 30 and 30 the rods 31, 31 will operate bell crank 31", 31 theends of which work in channel grooves on the shafts 24?, 24 that deliverthe power to the reversible friction drives. The lever 32 operates thesame as the lever 13 and through the linking rod 32 operates the lowerclutch member 29. Rigid on each shaft 2 and 24 are a pair of frictiondriving conical elements facing each other as 2?, 2e" and 24, 24 Themembers of each set may be alternately shifted to contact the elements23 or 23 of the proper assembly, or may at will be thrown out of anycontract into a neutral position.

It will be noted that when one or either of these reversible clutchesare in action, it will operate its screws jack member 23, 23 and rockthe arms 22 and 22 up or down and thereby adjust the position of theouter drum. Mounted on the outer ends of these arms 22 and 22 is aUshaped bar 33 on which is a level 34. By watching the level, the armsof the cutter drum may be adjusted so that the cutter drum stands level;In order to cut to adesired grade, a string 35 is strung upon grade pegsand an adjustable guide 36 is bolted to the arm 21. This guide is madeto follow the line 35 and the cutter drum will cut to such grade. Thecutter drum revolves in the direction of the arrow, Fig. l and as itcuts the earth, the cuttings are collected in the channel shapedsections 37 later described and are carried over the top and dumped onthe conveyor 38. This conveyor is transversely arranged immediately inthe rear of the drum 10 as seen in Figs. 1 and 2 and is driven in thedirection of the arrow by the following mechanism. On the shaft 7 ismounted a bevel gear wheel 39 which drives another bevel gear wheel 40which is mounted on the shaft 41. On the lower end of the shaft 41,vertically rotatable in bearings 41, 11 seen in Fig. 1, is mounted abevel gear 42, which drives an- Laeaooe other bevel gear wheel 43, whichis mounted on a-shaft which carries sprockets that drive the conveyorbelt 38. It will be noted that the conveyor will dump the excess dirt atthe side of the road.

W hen it is necessary for the machine to move from one place to another,the cutter drum is elevated until it clears the ground and by the actionof the levers 13, the clutch is disengaged and the machine is thendriven in the same manner as an ordinary caterpillar tractor. Thesprocket wheels 44 driven from'the tractor differential become thedrivers and the machine is guided by the steering wheel mechanism 45.

Referring to Figs. 5 and 6; form members 47 extend from the periphery ofone drum head 48 of the cutter to the other, being rigidly secured bybolts 47 These forms have their forward faces 47 substantially lying inradii of the drum 10, while their rear faces slope rearwardly as at 47The knives 49 are preferably of steel and are bolted, each, as at 19 tothe top of a form 47, their cutting edges 49 lying in a circle of largerdiameter as seen in Fig. 5. The dirt collectors are channel shapedrecesses 37 forming a plurality of shoveling elements, each recess 37 isformed between the under side of a projecting knife 49, the front face47 of its form member -17 and the rear face 47 of an adjacent formmember 47. These knives can be unbolted when sharpening is necessary.The knives are spirally arranged on the drum as seen in Figs. 2 and 6.

Such modifications may be employed as lie within the scope of theappended claims.
